Biography: 

Professor Bezabeh specializes in the evaluation and design of timber and timber-hybrid structures for earthquakes and strong winds. Prior to joining McGill, he worked as a Scientist/Technical Coordinator at . At RWDI, he coordinated the technical teams tasked with finding solutions to challenges linked to the wind design of tall and complicated buildings. These solutions involved wind tunnel testing and dynamic structural analysis. He received his Ph.D. and M.A.Sc. from the , Canada, in 2021 and 2014, respectively. He developed a displacement-based seismic design guideline for a novel steel-timber hybrid structure as part of his M.A.Sc. project at UBC, which was funded by the NewBuilds network initiative. He spent four years as a visiting research student at and conducted numerous wind tunnel studies at Western's and . His doctoral work developed new performance-based wind design frameworks for tall buildings. The frameworks are included in the new and the published by . He also spent a semester at 听developing听closed-form solutions for the seismic response of self-centering structural systems through the . At the World Conference on Timber Engineering (WCTE), he received the in 2018. He is currently a member of the ASCE's of the SEI Technical Activities Division.

Professor Bezabeh's research focuses on promoting resilient and sustainable urban development through tall timber buildings. In particular, he is interested in performance-based wind and seismic design of tall timber and hybrid buildings, seismic risk assessment of mass timber buildings, self-centering systems, uncertainty modeling and propagation, aeroelastic instability of structures, wind directionality, hybrid aeroelastic wind tunnel testing, the inelastic response of tall buildings with supplemental damping systems, and near-collapse behavior of structures subjected to strong non-synoptic wind systems.
